A method and apparatus providing a graphical user interface (GUI) that automatically determines timing groups and path groups for a circuit representation. In a first GUI display level, the GUI displays each path group in the circuit and allows the user to change the timing constraints for each path group. In addition, the GUI indicates whether each timing group is activated by a rising or falling clock signal. In addition, the user can define subpaths of a path group. After timing analysis software has analyzed the circuit, by clicking on a timing group in the first GUI display level, the user can view a second GUI display level, which shows details of the paths in the indicated timing group. By clicking on a path in the second GUI display level, the user can view a third GUI display level, which shows a list of each of the elements in the indicated path.
